Power and performance for your entire system
Kenwood's Performance Series KAC-7005PS 5-channel amplifier can take care of your entire car audio system's power requirements, and then some. Start with 40 watts RMS of musical clarity to every one of your front and rear speakers, then factor in up to 500 watts RMS for your subs — it all adds up to clear, loud, and rockin' sound in your car. Got a really nice set of speakers you want to drive? You can also bridge the amp into 3-channel mode and send 100 watts RMS to each of your front speakers, along with that 500 watts of bass power.

Reliability is key
This Performance Series car amp offers long-term reliability and superior sound quality in a compact, no-nonsense package. A rugged cast-aluminum heatsink and a cooling fan keep this amp running at optimal temperatures, even when you're pushing your system hard. This versatile amp features separate adjustable crossover filters for the front, rear, and subwoofer channels, as well as a bass boost, so you can dial in exactly the tone you want.

My system has plenty of power. Who needs an amp?

You might think you don't need an amp because you have a 400-watt system in your car, or because your new stereo puts out 50 watts a channel. But those are peak wattage ratings, which may boil down to 15 or 20 watts per channel, using the more realistic RMS rating. An amp sends your speakers the power they need to deliver your music with clarity and impact, whether you're using factory speakers or high-performance components. And low-frequency reproduction requires lots of power, so an amp is an absolute must if you're adding a sub to your system.

Product Research

Features

Multi-Channel Design: The KAC-7005PS is basically three amps
built into one chassis, two full-range 2-channel amps (A and B), typically powering
the front and rear speakers, and one mono amp to power a subwoofer. Either of the
full-range amps can also be bridged to one channel.

CEA 2006 Compliant: The amplifier's power and signal to noise
ratio specifications are measured according to CEA-2006 standards, developed by
the Consumer Electronics Association (CEA). These standards allow you to accurately
compare the rated power output of all CEA 2006-compliant amplifiers. Manufacturers
who adhere to the standards can display the CEA 2006 logo on their products and
packaging. The CEA-2006 compliant power output is 40 watts RMS x 4 (into 4Ω,
20-20,000 Hz, no more than 1.0% THD+N, 14.4 volt power supply) plus 300 watts RMS
x 1 (into 4Ω, 20-200 Hz, no more than 1.0% THD+N, 14.4 volt power supply).
The CEA-2006 compliant signal to noise ratio is 80 dBA (at 1 watt into 4Ω).

Specifications: The manual also lists these non CEA-2006
compliant specifications:

Cooling Fan: There is a cooling fan
to help dissipate heat and ensure cool, reliable operation. Make sure
not to block the vents or the fan when installing the amplifier.

Controls

Input Sensitivity: The KAC-7005PS features independent gain
controls for the front, rear, and subwoofer channels. The input sensitivity of
each is adjustable from 200 mV to 5.0 volts.

High-Pass Filter: The front and rear amps have individual
switches to set the built-in crossovers to high-pass or off (full-range). The
crossover points are independently adjustable from 50-200 Hz. The high-pass
crossover slope is 12 dB/octave.

Low-Pass Filter: The subwoofer channel's low-pass crossover
is always engaged (it cannot be bypassed). The crossover point is adjustable from
50-200 Hz and the slope is 24 dB/octave.

Bass Boost: The subwoofer's bass boost circuit is centered at 40 Hz;
boost is variable from 0 to +18 dB.

Connections

Power And Ground Terminals: The amplifier features screw
terminal power and ground terminals. They will accommodate spade connectors up
to 0.55" wide.

Remote Turn-On Terminal: The remote turn-on is a screw
terminal that will accommodate spade connectors up to 0.35" wide.

Speaker Terminals: The five pair of speaker terminals are
screw terminals and will accommodate spade connectors up to 0.35" wide.

Signal Inputs: The amplifier features three pair of RCA input
connections, A, B, and Sub.

Fuses: Two 40-amp ATO fuses are installed in the amplifier
chassis.

Kenwood quality

Written By R. L. Sr., Courtland, VA on Monday, February 16, 2015

I used the amp to power door speakers, back speakers under the window, and the subwoofers in a box. I did good! The sound is like a being at a concert! I listen to jazz, raggae, R&B, pop, and old hip hop and ALL of it is superb! I have always been a Kenwood fan since I was 19 years old. I have a Kenwood stereo in the house that still sounds good! This amp is great! I am proud and thankful for the choice I made.

Good Amp. Difficult controls.

Nice 5 channel amp with plenty of power and good sound to power 4 speakers and a subwoofer. You don't have to worry about two amps and two power cables. The controls for the gain and pass through and bass boost were tiny and hard to see even with a magnifying glass. I wanted to make sure the frequency filter was off because I was filtering it through the head unit, but I could not see how to make the switch and could not tell if it was on or off. The gain adjustment had poor markings and tiny tiny little slots to turn it with a tiny little screwdriver and an itsy bitsy marker that I could only see with a magnifying glass.

great amp

Amp provides good clean power for quality sound. I have not hooked up the sub yet, but am very happy with the power to my Polk 6" speakers. They sound clean and get loud with no distortion on this amp.
